HEAD LOSSES ANALYSIS IN SYMMETRICAL trifurcations OF penstocks - high PRESSURE PIPELINE SYSTEMS CFD C. A. AGUIRRE , R. G.

Systems using trifurcations allows flow of water to provide several turbines operating at the same time. This arrangement presents smaller assembly costs in comparison of independent pipeline systems. However this installation can generate high LOSSES in the system. This study focuses the quantified LOSSES as a function of the volumetric flow rate, using computational fluid dynamics (CFD). To determine the coefficient of LOSSES were analyzed three mesh settings: hexahedral, tetrahedral and hybrid, considering steady state flow. Based on the literature, the k- turbulence model, with refinement near wall elements, quantified the y plus.
